How to Apply Castor Oil on Hair

How to Apply Castor Oil on Hair

Knowing how to apply castor oil on hair correctly can make all the difference in results. Here's a step-by-step guide to ensure effective application:

Step 1: Dilute the Oil

Step 1: Dilute the Oil

Castor oil is highly viscous, so it’s best diluted with a carrier oil such as coconut, almond, or jojoba. Mix in a 1:1 ratio for easier application and to prevent buildup.

Step 2: Warm the Mixture

Step 2: Warm the Mixture

Warm the oil mixture slightly by placing it in a bowl of hot water. This enhances absorption and provides a soothing scalp experience.

Step 3: Apply to the Scalp First

Step 3: Apply to the Scalp First

Section your hair and use your fingertips to apply the oil directly to the scalp. Massage in circular motions to stimulate circulation.

Step 4: Spread Through Hair Length

Step 4: Spread Through Hair Length

Distribute the remaining oil through the lengths and ends of your hair using a wide-tooth comb to ensure even coverage.

Step 5: Let It Sit

Step 5: Let It Sit

Leave the oil on for at least one hour, or overnight for deeper conditioning. Use a shower cap to prevent mess.

Step 6: Rinse Thoroughly

Step 6: Rinse Thoroughly

Because castor oil is thick, washing it out properly is key. Start by applying conditioner before shampooing—it helps break down the oil. Follow with a sulphate-free shampoo. A keratin-based formula, such as Tresemme Keratin Smooth Shampoo, is an excellent choice to maintain softness and reduce frizz post-treatment.

How to Apply Castor Oil on Eyelashes and Eyebrows

  • Choose pure, cold-pressed castor oil to ensure it’s safe and effective for delicate skin around your eyes.
  • Use a clean spoolie brush, cotton swab, or a clean fingertip for application.
  • Dip lightly into the castor oil—a little goes a long way.
  • For eyelashes: Carefully apply the oil along the base of your lashes, similar to applying mascara. Avoid getting oil into your eyes.
  • For eyebrows: Brush the oil through your brows, coating hairs evenly to nourish follicles and encourage growth.
  • Apply nightly before bed to let the oil work its magic overnight.
  • Remove any excess in the morning with a gentle cleanser or warm water.
  • Be consistent—results typically appear after 4 to 6 weeks of regular use.

Pro Tips for Using Castor Oil in Your Hair Care Routine

Pro Tips for Using Castor Oil in Your Hair Care Routine

  • Frequency: Once or twice a week is sufficient. Overuse can lead to residue build-up and greasiness.
  • Hair Type Consideration: Best suited for dry, thick, or curly hair. Fine or oily hair types should use smaller amounts and mix with lighter oils.
  • Avoid Mistakes: Always dilute castor oil and avoid applying it to freshly washed hair—it adheres better to hair that’s not squeaky clean.
  • Test for Allergies: Conduct a patch test before your first application to rule out any sensitivities.
  • Be gentle with Eyelashes and Brows: The skin around your eyes is delicate—avoid rubbing or tugging.
